The Washington State Noxious Weed Control Board adopted the 2021 Washington State Noxious Weed List on November 10, 2020, adding a new Class A species, Turkish thistle (Carduus cinereus), which was recently found close to Washington in northeastern Oregon and adjacent Idaho. The State Board also adopted changes to the scientific names of several noxious weed species:
- Annual bugloss is now Lycopsis arvensis;
- Japanese knotweed is Fallopia japonica;
- Bohemian knotweed is Fallopia x bohemica;
- Ravenna grass is Tripidium ravennae;
- Scentless mayweed is Tripleurospermum inodorum;
- White cockle is Silene latifolia;
- Meadow knapweed is Centaurea x gerstlaueri;
- Japanese eelgrass is Nanozostera japonica;
- Himalayan blackberry is Rubus bifrons.
Other changes made by the Washington State Noxious Weed Board, including modifications to WAC 16-750, may be viewed at: (https://www.nwcb.wa.gov/whats-new). The state list went into effect on January 1, 2021.
The San Juan County 2021 Noxious Weed List must be adopted by February 28th.
In order for this list to become accepted for San Juan County, it must be approved by the County Noxious Weed Control Board based on public input received at this meeting. The Weed Board requests the public’s insights about local weed distributions as well as suggestions for the 2022 weed list, closing April 30.
